Description
A flaw was found in the Linux kernel's erofs filesystem component. When an input/output (I/O) request for a file-backed mount is interrupted by a SIGKILL signal, the system incorrectly marks unused data blocks as up-to-date. This can lead to data integrity issues or the potential disclosure of stale or incorrect information to a local user.
